Consider the following statements regarding digital filters: 1. An elliptic (Cauer) filter exhibits equiripple behavior in both the passband and stopband. 2. For a given filter order and identical passband/stopband ripple deviations, Cauer filters possess a larger transition bandwidth compared to Chebyshev filters. 3. Exact linear phase characteristics cannot be achieved in causal Infinite Impulse Response (IIR) filters. Which of the statements given above are correct?
